Hi Aitch
I had the same thing re: potty training at night, in that DD was up alot in the evening last week. So, I put her cot into bed form, and gave her the potty in her room. Now there is no excuse.
She is still getting used to the freedom a bed gives her ( AKA not settling well) but last night was night 3, and she settled within 1.5 hours, which is much improved on the last two nights).
WRT the night-time nappy thing, we night-trained by accident. She has always had a wet nappy in the morning, but on day 1 of big girl bed, we checked on her before we went to bed (we normally don't because she is such a light sleeper, but I needed to be sure she hadn't done herself an injury!) and she had taken her pull-up off.
TBH, thought process was short - rather change a wet sheet than wrestle child into pull-up and face another 2 hours of settling. She woke at 2am, used the potty. In the morning, she woke up and was dry.
Last two nights, she was offered pull-up and declined. Both mornings she has woken up dry. Our only issue is that she then pours her potty on the floor, so her room still stinks of wee . But we are hoping the novelty will go in time.
Re: Poos, my inclination would be to skip the pull-up, see if DD can stay dry at night, and then there would be nothing to hold the poo for, IFYSWM. Would she do a poo on the potty, rather than toilet?
Sorry for such a long essay, but am amazed that DD has just 'got' toilet training, esp at night.
